Let $(M, D, J)$ be a strictly pseudoconvex hypersurface type CR manifold with $J$ integrable. Let $D$ be the kernel of a $1$-form $\eta_0$. As known the automorphism group is defined to be $$ CR = \{ …

I'm reading Gromov's notes http://www.ihes.fr/~gromov/topics/SpacesandQuestions.pdf and at page 7 they say that there is a unique second order differential operator $S$ from the space of Riemannian m …

Let $K$ be a semisimple compact Lie group. In here H.C. Wang defines a C-subgroup as a closed subgroup $U$ of $K$ such that the semisimple part of $U$ equals the semisimple part of the centralizer o …

I'm reading the paper Lê, Hôngvân(D-MPI-NS); Wang, Guofang(PRC-ASBJ-MSY) A characterization of minimal Legendrian submanifolds in $S^{2n+1}$. Compositio Math. 129 (2001), no. 1, 87–93. Let $x: L^n …

Let $(M^{2n+1}, D, J)$ be a strictly pseudoconvex CR sturcture on a compact $2n+1$-dimensional manifold, where $D$ is a nonintegrable distribution of codimension 1. The algebra of the infinitesimal CR …

Hello, I am reading the paper Futaki; Ono; Wang Transverse Kähler geometry of Sasaki manifolds and toric Sasaki-Einstein manifolds. J. Differential Geom. 83 (2009), no. 3, 585–635. For your convenie …

In reading Gauduchon's notes (cannot link them, anyway it is standard material) I ran into the following construction. Let $(M, \omega_0)$ be a compact symplectic manifold which is fixed. An almost c …

I'm reading Gauduchon's paper Hermitian connections and Dirac operators. For a fixed almost-Hermitian manifold $(M, g, J)$ let $\mathcal A(g, J)$ be the space of connections $\nabla$ s.t. $\nabla g = …

In this paper the authors give an explicit description of the eigenforms and spectrum of the Laplacian acting on $p$-forms on the round sphere $S^n$, apparently citing an unpublished computation of Ca …

This is a list of length one :) The $\partial \bar \partial$-Lemma allows a parameterization of the cohomology class $[\omega]$ of a compact Kaehler manifold $(M, \omega)$ by means of scalar function …

Let $P \subset \mathbb R^n$ be a Delzant polytope defined by inequalities $\ell_i(x) \geq 0, i=1, \ldots, d$. Of course, from the symplectic point of view, the inequalities $a_i \ell_i \geq 0$ still …

The pair $(SO(2n), U(n))$ is a symmetric pair. You can have a look at Kraemer's paper (Comp. Math. 1979), where in the table the author lists explicitly the complex representations of $SO(2n)$ on whic …

Let $P$ be a Delzant polytope in $\mathbb R^n$, given by a set of inequalities $\ell_i(x) > 0$ where $\ell_i(x) = \sum_k \mu_k^i x_k - \lambda_i$. In his paper http://arxiv.org/abs/0803.0985 Donaldso …
